The rocks in Cornwall are often too hard for this striking rock boring mollusc, so it is a rare find in the county. The shell itself is beautiful marked but it is also quite fragile, and easily broken. Shells are found on the south coast where there are softer rocks e.g. around St. Austell Bay, Helford Passage and Mounts Bay, where they are found in degraded Mylor Slate, fossilised timber and submarine peat deposits.

Photographs were taken in the St. Austell Bay Area of Cornwall, where new sites for this species have recently been found; and at Chyandour Rocks, Penzance, Cornwall.

Scientific and European Names:

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help
people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
